    Caesar’s Last BreathSam KeanLittle, Brown and Co., $28

    Julius Caesar could have stayed home on March 15, 44 B.C. But mocking the soothsayer who had predicted his death, the emperor rode in his litter to Rome’s Forum. There he met the iron daggers of 60 senators.

    As he lay in a pool of blood, he may have gasped a final incrimination to his protégé Brutus: You too, my son? Or maybe...

    Magma stored under volcanoes is mostly solid

    Most of a volcano’s magma probably isn’t the oozing, red-hot molten goo often imagined.

    Analyses of zircon crystals, spewed from a volcanic eruption in New Zealand, show that the crystals spent the vast majority of their time underground in solid, not liquid, magma, researchers report in the June 16 Science. The results suggest the magma melted shortly before the volcano erupted.

    Antarctica’s Larsen C ice shelf is within days of completely cracking

    The rift in Antarctica’s Larsen C ice shelf continues to rip. Researchers from Project MIDAS, which tracks the effects of a warming climate on the ice shelf, report that the crack grew 17 kilometers between May 25 and May 31.

    The crack has now turned toward the water and is within 13 kilometers of the edge of the shelf. Within days, the crack could reach the edge. When that happens, one...

    Deep heat may have spawned one of the world’s deadliest tsunamis

    Chemical transformations in minerals deep beneath the seafloor could explain why Indonesia’s 2004 mega-earthquake was unexpectedly destructive, researchers report in the May 26 Science. 

    The magnitude 9.2 quake and the tsunami that it triggered killed more than 250,000 people, flattened villages, and swept homes out to sea across Southeast Asia. It was one of the deadliest tsunamis in...

    Stunning images reveal glacial landscapes under the oceans

    View the slideshow

    The footprints of long-gone glaciers and icebergs are now frozen in time in a stunning new collection of images of Earth’s seafloor.

    The Atlas of Submarine Glacial Landforms is a comprehensive, high-resolution atlas of underwater landscapes that have been shaped by glaciers, largely in polar and subpolar regions, and provides a comparative look at how glaciers,...

    Ice particles shaped like lollipops fall from clouds

    Ice-Lolly\AIS LOL-ee\ n.

    A small ice particle made of a needle-shaped ice crystal and a single drizzle-sized water droplet

    Right now, somewhere in the world, it could be raining lollies. A 2009 research flight through clouds above the British Isles gathered ice particles with an unusually sweet look. Each millimeter-sized particle consisted of a stick-shaped piece of ice with a single...

    Crack in Antarctica’s Larsen C ice shelf forks

    The 180-kilometer-long crack threatening one of Antarctica’s largest ice shelves has branched out, new satellite observations reveal. The main rift in the Larsen C ice shelf hasn’t grown longer since February. But radar mapping shows that a second crack has split off from the main rupture like a snake’s forked tongue, members of the Antarctic research group Project MIDAS reported May 1. That...

    Radical idea could restore ice in the Arctic Ocean

    Leave it to a researcher who studies icy moons in the outer solar system to come up with an out-there scheme to restore vanishing sea ice in the Arctic.

    Ice is a good insulator, says Steven Desch, a planetary scientist at Arizona State University in Tempe. That’s why moons such as Jupiter’s Europa and Saturn’s Enceladus, among others, may be able to maintain liquid oceans beneath their...

    ‘Fossil’ groundwater is not immune to modern-day pollution

    Groundwater that has lingered in Earth’s depths for more than 12,000 years is surprisingly vulnerable to modern pollution from human activities. Once in place, that pollution could stick around for thousands of years, researchers report online April 25 in Nature Geoscience. Scientists previously assumed such deep waters were largely immune to contamination from the surface.

    “We can’t...
